My father came back from WWII with several problems, physical and otherwise.
He received a lot of help from the VA.
What was different back then was the VA; and the value that Americans had for returning servicemen.
Hear, hear!
My Dad came back from Korea with permanent hearing damage and got squat.
Dad was a strong, strapping giant of a man that was unflappably composed in the face of danger or adversity. Nevertheless,
I remember him wearing blast muffs to my sports nights because the cheering and roars of the crowd would cause his ears to ring so badly, it was intolerable.
